Graphing calculator.

• Three trigonometric functions are readily available in the keyboard: sine
(S), cosine (T), and tangent (U). Arguments of these functions
use angles in degrees (DEG):
In ALG mode:
In RPN mode:
• The inverse trigonometric functions available in the keyboard are the
arcsine („¼), arccosine („¾), and arctangent („À).
The answer from these functions will be given in the selected angular
measure (DEG, RAD, GRD). Some examples are shown next:
In ALG mode:
In RPN mode:
All the functions described above, namely, ABS, SQ, , ^, XROOT, LOG,
ALOG, LN, EXP, SIN, COS, TAN, ASIN, ACOS, ATAN, can be combined
with the fundamental operations (+-*/) to form more complex
expressions.
The Equation Writer, whose operations is described in
Chapter 2, is ideal for building such expressions, regardless of the
calculator operation mode.
